Definitions

  • the present invention concerns a firework comprising a safety plug provided with mechanical delay fuse, and safety plug with mechanical delay fuse to be used in such a firework.
  • the invention concerns a firework with a safety plug provided with "mechanical" delay fuse, i.e. that does not make use of active material such as that of traditional delay fuses, increasing the safety in the use of the same fireworks.
  • the invention concerns specifically also such a safety plug.
  • Fireworks are known with delay fuses using active chemical substances, as in EP 00257032 , US 3113519 , US 3895577 .
  • Such a firework type to the knowledge of the Applicant, is the sole that is today known and legally used (there are on sale also fireworks which do not use any type of delay).
  • the traditional firecracker 10 is constituted by an elongated container 14 (usually a cylinder) in which it is placed the active material 12 and by a matchcord 13 that serves for the triggering of said active material.
  • the matchcord 13 is connected to the delay fuse 11.
  • Even the delay fuse is composed by a material which is considered as active.
  • the first is determined by the fact that the law provides a maximum limit of active material that a producer can hold and that can be transported with separate shipping, therefore the productivity cannot be increased because of transportation costs, as well as because of the impossibility of producing higher amounts of products.
  • the second is the low safety that one has firecrackers (and with fireworks in general), which can not explode while they are held in the hand, without the explosion provoking wounds.
  • a firework comprising a wrapping, an internal active substance as well as a safety plug that closes an aperture of said wrapping and to which a triggering matchcord is connected, characterised in that said safety plug comprises a delay fuse and further comprises:
  • the dimension of said through-hole, at the end of the safety plug facing the interior of the firework is close to the dimension of the triggering matchcord, whilst the dimension of the through-hole on the opposite side is sensibly larger then the triggering matchcord, so as to be able to receive a suitable quantity of gluing material that constitutes said fixing and sealing means.
  • said triggering matchcord (140) is fixed by hot gluing.
  • the safety plug comprises a main hollow body presenting a lower base and an upper edge, as well as a spout connected to said lower base on the side facing the interior of the firework, the spout and said lower base being crossed by said through-hole.
  • the safety plug comprises a disk, to the side of the disk facing the interior of the firework being fixed and spout, the disk and the spout being crossed by said through-hole, being fired provided means for fixing said disk to the firework.
  • the safety plug comprises a body hollow or full with the form of a frustum of cone, with a through-hole, said body being at least partially inserted in the firework, being further provided means for fixing said body to the firework.
  • said fixing means are constituted by interference fins which interfere the internal surface of the firework.
  • the firework is a firecracker with a cylindrical body, said plug presenting a circular cross-section and being inserted in said cylindrical body, closing it from outside.
  • a plug with delay fuse for a firework comprising:
  • the dimension of said through-hole, at the end of the safety plug which is orientable towards the interior of the firework is close to the dimension of the triggering matchcord, whilst the dimension of through-hole on the opposite side is sensibly larger than the triggering matchcord so as to be able to receive a suitable quantity of gluing material which constitutes said fixing and sealing means.
  • the plug is constituted by a material suitable for the hot gluing of said triggering matchcord.
  • the plug comprises an hollow body presenting a lower base and an upper edge, as well as a spout connected to said lower base on the side orientable towards the interior of the firework, the spout and said lower base being crossed by said through-hole.
  • the plug comprises a disk fixable to the end of the firework, on the side of the disk orientable towards the interior of the firework being fixed a spout, the disk and the spout being crossed by said through-hole, being further provided means for fixing said disk to the end of the firework.
  • the plug comprises a body hollow or full with the form of a frustum of cone, with a through-hole along its principal axis, said body being at least partially insertable in the firework, being further provided means for fixing said disk to the end of the firework.
  • said fixing means are constituted by interference fins which interfere with the internal surface of the firework.
  • the plug presents a circular cross-section and is insertable in a firework with cylindrical body, or in that it is applicable to the outside of the same, for example by screwing, gluing, or interference.
  • FIG 2 it is shown the safety plug 120 that, according to the invention, among other things, substitutes the delay fuse of the prior art.
  • the safety plug has a cylindrical body 123 with an upper edge in relief 122 and a lower spout 121.
  • a spout 121 presents a through-hole 125 for inserting a triggering matchcord (shown on the following figures).
  • the body 123 is hollow, with a base 124 whereon the spout 121 connects directly, the base being bored for the same reason.
  • Such a safety plug is placed, with reference to figure 3, at an end of the firecracker, and the walls of the body 123 interfere with the cylinder 130 which forms the external wall of the firecracker itself, thus fixing such a safety plug to the cylinder itself.
  • the upper edge 122 of the safety plug plays as abutment that hinders the deeper insertion of the safety plug 120.
  • the matchcord 140 is inserted in the safety plug through the through-hole 125.
  • the end 144 of the matchcord is fixed to the hole of the spout 121, which constitutes an actual delay fuse, so that the firecracker will explode exactly at the internal ends of the matchcord, a position that is well determinable by using the device according to the invention.
  • the height of such safety plug or more precisely of such a delay fuse
  • the form of the safety plug 120 according to figure 2 is only one of possible forms for such a device. Indeed, according to figure 5, it is for example possible a form 120' constituted by a disk 122' and a spout 121'. In figure 7 instead, the form of the safety plug 120" is that a frustum of cone. The hole is through and oriented always preferably along the principal axis.
  • fixing means (not shown) to the cylindrical body of the firecracker, because the walls of the safety plug cannot exert a pressure on said cylindrical body.
  • the fixing means can be constituted by fins that exert such a pressure (cf. Figure 6 in the case of embodiment with disk and spout).
  • the matchcord can be restrained into the hole of the spout or even glued to it, for example by hot gluing.
  • the hollow models of the safety plug allows to save material, on one hand, and, on the other hand, to obtain an element which subsequently to the explosion does not belong sufficient inertia to wound persons or things.
  • the dimension of the safety plug is much variable. Indeed, one can even eliminate the spout, renouncing to the delay, owing to the shorter length of the matchcord, however enjoying the advantage of a well-determined triggering point.
